A coaxial connection is perfect for transmitting a digital audio signal. You can get better sonic results with it than with an optical connection. This is due to the lack of signal conversion that occurs in the case of a coaxial connection. A coaxial connection may support a higher signal resolution (most commonly 24-bit/192kHz). For optical connections, the maximum throughput is typically limited to 96 kHz.
The main disadvantage of a coaxial connection, however, is the greater risk of transmitting interference along with the useful audio signal. Therefore, when choosing a coaxial cable, special attention should be paid to its shielding.
Coaxial connections do not have enough bandwidth to support high-quality surround sound formats: Dolby True HD or DTS-HD Master Audio. Thus, in a modern home theater system, the possibilities of its use are very limited. The bandwidth of the coaxial connection is 52 Mb/s
Which connection to use?
The answer to this question depends on the type of devices you want to connect. If you are going to send a digital audio signal and you are considering a coaxial or optical connection, we advise you to choose the former. We know from experience that using a coaxial connection we can get better sound quality. It's all about a higher level of detail and better dynamics.
If you have a home theater system, the best solution will undoubtedly be to use the HDMI connector. As we have already mentioned, it allows you to transmit audio and video signals with one cable, which significantly reduces the number of cables. In addition, due to the high bandwidth, you don't have to worry about signal quality limitations.
ANY QUESTIONS?????
BUT XLR will be defo better from coaxial in audio I talk about sound quality
